Came back to the printer and found a golf ball sized glob of plastic melted and stuck to the bottom of the print head.
I think I need to get that print head off and work at freeing that blob, without damaging the print head off course.
Other suggestions?
Thank you.
Next day…
I was able to partially disassemble the printer, so I could better see and access that blob. After trying to gently pry it loose with a flat screwdriver, I went for a small pliers. Better leverage and gently tipping it this way and that, loosened the blob allowing me to remove it.
Am now running a few test prints and it is running well.
But the clear Creality media seems to be the problem!
After the first row, the object separated from the base, stuck to the point head, and melted plastic started filling in and pushing out the sides.
